Hi... this is a little confusing to me but I'll throw it out there.
We had a NFS share being used in VMware to hold ISOs and VM templates. CIFs was also enabled on this filer but did not appear to be authenticating correctly with AD. I decided to go through the CIFs setup wizard again after troubleshooting unsuccessfully on how to create a CIFs share. Immediately after the service was stopped I lost permissions to my folders in the NFS datastore in vsphere. The datastore is still connected in VMware (shows normal in the console) but the folders have disappeared... (I presume that somehow VMware lost permissions to this volume even though it's still connected. I can now map a CIFS share (with full NTFS permissions) to the same level that the other folders are on and see the other directories... but it is list access only when I browse the old VMware unix directories.
I've been reading through TR-3490 after some other recommendations on the forum so I've picked up a little more background but I'm still kind of lost as to how to restore VMware's access to these folders.
